can't stop breaking my G

i don't get it, my factory strings lasted from august till december, then i broke my G while popping
i bought a new set of strings, my G didn't last 3 weeks, bought another G, this one didn't last for a month an a half. and the strange thing about it is that it's just the core which breaks, leaving the surrounding intact.
does got to do with the way i play, or do i only buy crappy string? or is it something like temperature or humidiness i should take care of?

1. Where did the string break? If it was the same place each time there might be something rough on the bass that needs sorting out.

2. Did all the break occur when you were popping? If not, it would be useful to know the other techniques you use - a heavy hand is more likely to break strings than one that has learned to dance lightly.

well, my last broken G broke just on the bridge
the part where the string stops goin / and starts going _
the g before that broke an inch, maybe 2 inch past the bridge, so i guess there something out there
and on the G i only pop and tab(i even don't use an plectrum) so i wouldn't know if that would destroy an g so easily

i had this problem really bad on a warwick i had, and it turned out there was a sharp ridge that the casting process left where the string lied. i filed it down - no more broken strings. (at least, not one every other gig like it was before)

also, your technique is probably a bit heavy - the combination of quality strings and lightening up my technique has limited my broken strings to one every few months.

I've only broken about three strings in my 16 year playing career (albeit 'career' in the amateur sense of the word) and, as I recall, all three of those were through tuning up (or was one when someone else was playing the bass? It's a long time ago now .... ). That includes a moderate amount of slapping and popping.

The fact the string didn't break in the same place each time suggests the bridge probably isn't to blame (although check to see that it's smooth). I'd highly recommend working on a gentler technique - you don't have to pull the string two inches off the fretboard to get the right kind of snap!

I broke 2 G strings last night. My first one broke because i popped it a little too hard, after I replaced it i tuned it a little flat and stetched it out a little and it broke again. The strings i had on were Ernie Ball Super Slinkys (which are nickel wound) and the only replacements i had were a new set of rotosounds(which are stainless steel) so i went and replaced the whole set.

By the way, this is my first time using stainless steel and so far I really like'em

i had the same problem on my peavey foundation bass,it seems that it was a design flaw in the sense that the strings had to be overtightened to tune,i will try to explain to best i can,when i would try to tune my G string it would either snap or come out of the tuner guide,i brang it to my luthier and he looked it over and said the bridge position was too close to the neck causing the strings to be overly taunt,the only way to remedy was to reposition the bridge further away from the neck,a temporary solution was to lighten the string gauge,i opted for the latter of the two solutions,it worked most of the time,i did'nt like the change in strings so i sold the bass, i hope this helps, if you are unsure bring it to a pro!
